OAKLAND — Daniel Boggan Jr. has been named Alameda Health System interim CEO.

Boggan will take over Dec. 15, replacing Wright Lassiter III, who is leaving for a job with the Henry Ford Health System in Michigan.

Boggan, 68, served on the health system”s board of trustees from 2005 to earlier this year and was on the search committee that hired Lassiter in 2005.

The interim appointee has more than 40 years of experience in public administration, including Berkeley city manager from 1981 to 1986 and chief of staff for former Oakland Mayor Ron Dellums. He is an Oakland resident and was a UC Berkeley vice chancellor and senior vice president and chief operating officer for the National Collegiate Athletic Association.

The hospital system is conducting a national search for a permanent CEO.

The financially troubled public hospital system has been unable to pay down its long-term debt to Alameda County, which was supposed to be down to $110 million by this past summer, but now is $162 million.

The hospital”s continuing financial woes have been blamed on

glitches in installing a new electronic health records and billing system, which led to major problems paying bills.

Also contributing, hospital administrators say, were delayed federal reimbursements and the cost of folding two struggling hospitals — Alameda Hospital and San Leandro Hospital — into the county safety-net system. Alameda County supervisors hired a Concord company in November to review Alameda Health System”s finances and operations.

Alameda Health System also includes Highland Hospital in Oakland, John George Psychiatric Hospital, Fairmont Hospital rehabilitation center, and wellness centers in Oakland, Newark and Hayward.
